<div class="textblock"><p>Interface of an object which can receive events. </p>
<p>Many of the engine's classes inherit <a class="el" href="classirr_1_1_i_event_receiver.html" title="Interface of an object which can receive events.">IEventReceiver</a> so they are able to process events. Events usually start at a postEventFromUser function and are passed down through a chain of event receivers until OnEvent returns true. See <a class="el" href="namespaceirr.html#ac9eed96e06e85ce3c86fcbbbe9e48a0c" title="Enumeration for all event types there are.">irr::EEVENT_TYPE</a> for a description of where each type of event starts, and the path it takes through the system. </p>

<p>Called if an event happened. </p>
